To slice and dice is to break a body of information
down into smaller parts or to examine it from different viewpoints so
that you can understand it better. In cooking, you can slice a vegetable
or other food or you can dice it (which means to break it down into small
cubes). One approach to dicing is to first slice and then cut the slices
up into dices. In data analysis, the term generally implies a systematic
reduction of a body of data into smaller parts or views that will yield
more information. The term is also used to mean the presentation of information
in a variety of different and useful ways.
This term can be compared to drilldown, which is the process of dividing
an information area up into finer and finer layers in a hierarchy, but
with the purpose of narrowing in to one small area or item.
